Microzooplankton grazing and phytoplankton growth in marine mesocosms with increased CO2 levels
Microzooplankton grazing phytoplankton growth marine mesocosms CO2 levels
2010/1/18
Microzooplankton grazing and algae growth responses to increasing pCO2 levels (350, 700 and 1050 μatm) were investigated in nitrate and phosphate fertilized mesocosms during the PeECE III experiment 2...
Coupling of heterotrophic bacteria to phytoplankton bloom development at different pCO2 levels:a mesocosm study
heterotrophic bacteria phytoplankton bloom development pCO2 levels
2010/1/18
The predicted rise in anthropogenic CO2 emissions will increase CO2 concentrations and decrease seawater pH in the upper ocean. Recent studies have revealed effects of pCO2 induced changes in seawater...
Climate-mediated changes to mixed-layer properties in the Southern Ocean:assessing the phytoplankton response
Climate-mediated changes mixed-layer properties Southern Ocean phytoplankton response

Concurrent changes in ocean chemical and physical properties influence phytoplankton dynamics via alterations in carbonate chemistry, nutrient and trace metal inventories and upper ocean light environ...
Effects of increased atmospheric CO2 on small and intermediate sized osmotrophs during a nutrient induced phytoplankton bloom
atmospheric CO2 intermediate sized osmotrophs nutrient induced phytoplankton bloom
2010/1/15
We report the transient population dynamic response of the osmotrophic community initiated by a nutrient pulse in mesocosms exposed to different pCO2 levels. Differences in phytoplankton and heterotro...

The influence of dissolved organic carbon on bacterial phosphorus uptake and bacteria-phytoplankton dynamics in two Minnesota lakes
dissolved organic carbon bacterial phosphorus uptake bacteria-phytoplankton dynamics two Minnesota lakes
2014/4/21
The balance of production in any ecosystem is dependent on the flow of limiting nutrients into either the autotrophic or heterotrophic components of the food web. To understand one of the important co...
